He’s jammed the White House on Benghazi, health care and a host of other issues — investigations that have apparently turned House Oversight Committee Chairman Rep. Darrell Issa, the Southern California Republican, into a star speaker in the GOP world.

Now he’s been tapped to keynote the big Concord/Merrimack County GOP’s Annual Lincoln Day Dinner in New Hampshire, home to the “first in the nation” 2016 primary.

Issa made news this week for being tagged as the richest member of Congress in new study by the Center for Responsive Politics, which estimated his net worth in 2012 as $464 million.

But it looks like the California Congressman is planning to mine some Republican gold — backers, donors and attention — with his increased profile on the national level.

“From Operation Fast & Furious to the IRS targeting scandal to the disastrous implementation of the President’s health care plan, Congressman Issa has been standing with the American people to protect their right to know what this government is doing and we are very excited that he is coming to New Hampshire to headline our annual event,” said Kerry Marsh, Chair of the Concord GOP, in a statement today announcing Issa’s appearance. “Every year, this dinner gets bigger and has become one of New Hampshire’s signature political events.”

The office of Issa, who’s been a thorn in the side of the Obama administration for his investigative vigor — Dems call it harassment — released a statement that suggests he plans to be front and center on the political stage in both 2014 and beyond:

“There are two conversations that will shape the 2014 and 2016 elections and there couldn’t be a better place to start those conversations than in New Hampshire,” said Issa. “The first is whether or not the Republican Party can define itself as the party that supports individual opportunity and American entrepreneurship so that you can be the engine of your own prosperity, not government. The second comes down to how comfortable the American people are with a large, invasive and powerful government that escapes accountability with no check-and-balance.”

In other words: it’ll continue to be pedal to the metal on that Oversight Committee work.

And he’ll be around to “shape the conversation” of the 2014 and 2016 elections.
